Due to the strong effect of the composite fabrication method on the structural capacitor performance, the structure development should be performed with the involvement of composite engineers. Structural development should be conducted with inclusion of the electrical contacts in the overall design.
This first report of a structural capacitor was a decade later confirmed by Carlson et al. , , who reported a capacitance of 450 nF/m 2 at 0.1 Hz, as obtained using PET of thickness 50 µm as the dielectric film. Other than PET, dielectric polymers used include polyamide and polycarbonate .
Since service life and safety are essential for structural capacitors, dielectric structural capacitors are more promising than structural supercapacitors, in spite of the fact that the capacity for small-scale energy storage tends to be greater for a supercapacitor than a dielectric capacitor.
The modification of a structure to render the capacitor function involves the positioning of a dielectric film between the electrodes, which are an electronic conductor, commonly the continuous carbon fiber laminae that serve to reinforce the composite.
A parallel-plate capacitor in the form of two electrodes sandwiching a dielectric layer actually consists of three capacitors in series, namely the capacitance Cv of the volume of the dielectric material and the capacitance Ci of each of the two interfaces between the dielectric layer and the two electrodes.
There are two main types of capacitors, namely dielectric capacitors (also known as electrostatic or electrolytic capacitors) and supercapacitors (also known as ultracapacitors). The former is purely electrical in nature, whereas the latter is electrochemical in nature.
